In contrast, the saturation and cut-off regions allow bipolar transistors to be used as switches because there is little electrical resistance between emitter and collector in the saturation region and little current flows in the cut-off region. Therefore, an amplifier circuit can be configured using the active area. When a bipolar transistor is in the active region, the collector current is basically h FE times the base current. Therefore, if the emitter and collector terminals are reversed, a bipolar transistor has a much lower h FE and does not function as intended. (For example, in the case of an npn transistor, the collector and the emitter on both sides of the p region of the base are n regions, which look the same.) However, the dopant concentrations in the collector and emitter regions are quite different. The structure of a bipolar transistor looks symmetrical. Two types of bipolar transistor are available, known as npn and pnp, based on the type of junction. INDUSTRY STANDARD SGS-THOMSON NEAREST SGS-THOMSON PREFERRED. Since the bipolar transistor was the first transistor to be invented, when one simply says "transistors," it sometimes means bipolar transistors. Whereas a field-effect transistor is a unipolar device, a bipolar transistor is so named because its operation involves two kinds of charge carriers, holes and electrons.

You can download the results of your (filtered) selection to Excel by clicking the Download Excel button.Bipolar transistors are a type of transistor composed of pn junctions, which are also called bipolar junction transistors (BJTs).

You can change the order of the columns by dragging and dropping the columns to the desired position.

You can check the columns you want to see.

To add or remove columns with parameters click on the Add/Remove parameters button on the top right.

But you might already have a suitable substitute in your parts drawers.

To hide the row with filtering options, click on the grey bar with arrows below the options. If you dont have that particular type, a transistor cross-reference book can sometimes help you to find a compatible part.

You can compare two or more type numbers by selection the checkboxes for the type numbers and click on Compare. The cross reference comparisons generated by this tool are automatically calculated based on information obtained from a variety of sources.

You can find more information about a type number by hovering over the type number and click on one of the links in the pop-up.

The common characteristics are parameters with the same value for all type numbers.

Or use the sliders by dragging the handlers or fill in the fields.
